8 Claims.

This invention relates to improvements in shaker conveyers and more particularly relates to a new and improved means for laterally moving the pick-up vend of a shaker conveyer.

The principal object of my invention is to provide an efficient and simplified form of self-contained means of a novel construction, which is selectively operable to positively move the pick-up end of a shaker conveyer laterally either while the conveyer is in motion or is standing still.

This and other objects of my invention will appear from time to time as the following specification proceeds and with reference to the accompanying drawings wherein:

Figure 1 is a plan view of the inby end of a shaker conveyer trough line having a device constructed in accordance with my invention embodied in the inby end thereof;

Figure 2 is a View in side elevation of the inby end of the trough line shown in Figure 1 and drawn to a larger scale than Figure 1;

Figure 3 is an enlarged fragmentary view in side elevation of the inby end of the extensible trough of the trough line shown in Figures 1 and 2, with parts of the extensible trough broken away and with other parts shown in substantially longitudinal section in order to illustrate certain details of my invention;

Figure 6 is a View somewhat similar to Figure 5 but showing the cylinder and piston in transverse section and showing the pick-up member on the inby end of the extensible trough in a lowered position and in a central position with respect to the trough line;

Figure 7 is an enlarged detail fragmentary transverse sectional view showing certain details of my invention which are not shown in Figures 5 and 6; and

Figure 8 is a transverse sectional view taken substantially along line 8 8 of. Figure 4.

In the embodiment of my invention illustrated in the drawings, Figure 1 diagrammatically shows a portion of a shaker conveyer trough line I IB. Said trough line is reciprocably driven at its outby end from a shaker conveyer drive mechanism (not shown), in a manner well known to those skilled in the art, for moving material from the inby to the outby end thereof by the reciprocable motion of said trough line. Said trough line includes a swivel trough I I having a reciprocating trough I2 pivotally connected to its forward end for lateral movement along the ground about the axis of said swivel trough. Said swivel trough is so arranged as to permit the continuous flow of material along said reciprocating and swivel troughs to the outby end of the trough line, when the forward end of said reciprocating trough is in various positionsof lateral displacement with respect to the trough line.

A pick-up member or shovel I4 forms a forward continuation of the forward end of an extensible trough l5, which` extensible trough is mounted for extensible or retractible movement with respect to said reciprocating trough. Said extensible trough l5 is mounted on a ground engaging shoe I6 adjacent its rear end on legs I1, I'l extending along opposite sides of said reciprocating trough, and supporting the rear end of said extensible trough in cuttings discharge relation with respect to said reciprocating trough as it is extensibly or retractibly moved therealong. The forward end of said extensible trough is supported-on the forward end of the shovel I4.

A friction grip feeding mechanism I8 mounted on the forward end of the reciprocating trough I2 and extending in advance thereof, is adapted to be moved into engagement with said extensible trough during alternate strokes of the conveyer, for extensibly or retractibly moving said extensible trough with respect to said reciprocating trough in a manner well known to those skilled in the art. Said feeding mechanism is herein shown as being of a form similar to that illustrated in the Sloane Patent No. 2,318,808, dated May 1l, 1943, so need not herein be shown or described in detail.

Referring now to the means for positively moving the shovel Illand extensible trough I5 laterally about the axis of the swivel Il, a ground engaging shoe I9 is mounted in a guide frame 20, and when engaged with the ground, forms a means for lifting said guide frame above the ground and supporting said guide frame for movement with respect to said shoe in a direction transversely of the longitudinal center of the trough line.

The guide frame 20 is herein shown as being mounted beneath the shovel I4 for vertical adjustment with respect thereto, to elevate said shovel above the ground, and as having an open central portion 23 adapted to receive a cylinder 24, herein shown as being formed integrally with and extending upwardly from the. shoe I9. A pluralityof` aligned bosses 25,25 project from opposite side walls of said cylinder in a direction extending longitudinally of the trough and have rollers 26, 26 rotatably mounted thereon. Arms 2'I, 2'I extend from opposite ends of said cylinder in directions extending laterally of the shovel I4, and also forwardly and rearwardly from said cylinder, and have rollers 29, 29 rotatably mounted thereon and extending transversely of the shovel i4 in the same planes as the rollers 26, 26. Said rollers 29, 29 are similar to the rollers 26, 26, and said rollers 29, 29 and 26, 26 are guided in facing parallel spaced transversely extending channelled guides 39, 30, herein shown as extending upwardly from and as being formed integrally with said guide frame 2l), on opposite sides` of the open central portion'thereof. Said channelled guides and rollers thus form a means for slidably supporting said shoe on said guide frame, when said shoe is out of engagement with the ground, and for slidably supporting said guide frame on said shoe when said shoe is engaged with the ground and liftsithe end of the shovel Id above the ground.

The adjustable connection between the guide frame 29 and the bottom of the shovel I4 includes a link 33 extending for substantially the full width of said guide frame andv interleaving the forward portion of said guide frame and pivotally connected thereto by means of a transversely extending pivotal pin 34. The opposite end of said link interleaves the free end of a transversely extending plate 35 and is pivotally connected thereto by means of a pivotal pin 96. Said plate is secured at its forward end to the bottom of said shovel 'and extends in a rearward direction away from the bottom of the shovel I4 in a slightly downwardly inclined direction. Opposite sides of said plate are secured to side walls 3l, 3l depending from the bottom of the shovel and extending along opposite sides of the guide frame 29, to prevent dirt from getting inside of said guide frame. Said side walls also form a guide means for said guide frame to limit lateral displacement thereof. A link 39 interleaves the end of the said guide frame, which is opposite from the link 33, and is pivotally connected thereto by means of a pivotal pin 40. The opposite end of said link interleaves a cross head 4l slidably guided at its ends in facing channelled guides 42,v 42 formed integrally with the depending sides 31, 3l of the shovel I4. A pin @.3 pivotally connects said link to said cross head. The opposite end of said cross head is pivotally connected to an enlarged laterally extending forward end of a piston rod 44 by means of a pivotal pin 45. Said piston rod is extensible from acylinder 46 and extends from a piston 41 slidably movable 'within said cylinder.

Saidcylinder is secured to and depends from the bottom of a rearwardly projecting portion 8 of the shovel I4, which forms a continuation of said shoveland extends along and substantially conformsto the form of the extensible trough I5. Suitable huid connections (not shown) may be provided to admit uid under pressure to either the head .or piston rod ends of said cylinder.

' The 'admission' of fluid under pressure to the head end of said cylinder will thus move the cross 26 and 29, 29 for slidable movement along the' shoe I9 in a direction extending transversely of the shovel.

The means for slidably moving the guide frame 29V with respect to said shoe in a direction transversely of the trough I5 includes a piston 49 herein shown as being formed integrally with a piston rod 50, intermediate the ends thereof. Said piston rod extends beyond opposite ends of the cylinder 24 and is mounted at its ends in upright support brackets 5I, 5I, secured to and extending upwardly from the bottom of said guide frame 20. Said piston rod is drilled from its opposite ends to positions adiacent opposite sides of said piston, and is cross drilled to open into said cylinder, adjacent opposite sides of said piston, to admit fluid to one end or the other of said cylinder to move the guide frame 20, extensible trough I5, and shovel I4 along said shoe on the rollers 26, 29 and 29, 29 in one direction or another about the swivel I I.

During operation of the conveyor, the shoe I9 may be lifted clear of the ground and held in an elevated position by the admission of fluid under pressure to the piston rod end of the cylinder 46. When it is desired to elevate the forward end of the shovel I4 above the ground, either to lift said shovel over a roll on the ground or to position said shovel for moving laterally, fluid under pressure may be admitted to the head end of said cylinder 6 to depress said shoe and positively raise the forward end of said trough and shovel above the ground in the hereinbefore described manner. Fluid under pressure may then be admitted to Aone end or the other of the cylinder 24 through the drilled piston rod 59, depending upon the direction it is desired to move the Shovel, to move said guide frame and extensible trough and shovel in a transverse direction, preferably for the kfull length of travel of said piston.

Where it is desired that the shovel be moved laterally a distance further than the length of travel of said piston, fluid under pressure may be released from the head end of the cylinder 46 and admitted to the piston rod end thereof, to lift the shoe I9 above the ground, At the same time, the guide frame 20 may be returned to its initial position by admitting fluid under pressure to the opposite end of the cylinder 24 from which it was rst admitted. Fluid under pressure may then be admitted to the head end of the cylinder i6 to again lift the shovel lll above the ground, and at the same time fluid under pressure may be admitted to the cylinder 2li to further move said shovel in a lateral direction about the axis of the swivel II. These operations may be repeated until the shovel is inthe desired lateral position with `respect tothe trough line.

While I have herein shown `and described one form in which my invention may be embodied, it will be understood that the construction thereof and the arrangement of the variousparts may be altered without departing from the spirit and scope thereof.
